-.w IMPROVEMENT-IN LIQUID MEASURES.

The Seherlule referred to in these Letters Patent and making part of the same connected with spiral springs and valves, and also.

tubes and regulator connected with the same.

Description of the Accompanying Drawings.

Figure 1 is a side elevation. Figure ,2 is anend view of the measuring apparatus. n

Figures 3, 4, and 5, enlarged views of the valve and regulator. l

A represents the can which contains the liquid, and the apparatus` for measuring the same. f' y B, the upper interior apartment which contains the liquid, and which is sealed, or rather soldered, at the base or bottom of said apartment, so no liquid can pass below except through the aperture c' c', and by the use of the levend.

' C is a rod connected and attached to the lever d, on the outside and top of the can A.

The rod C has attached toit a spiral spring, i, which rests on the bottom of the apartment B, and is fastened at each end of' the same.

The rod C extends through said apartment, below and into and through the tube E into the measure a.

The tube E is stationary, and the upper end of the same is soldered to the bottom of. the apartment B, and the lower end extends through the upper partei the measure a and within about one-half inch ofthe bottom of the same.

To the lower end of the rod C, which passes through said tube, and into the interior of the measure a, is attached a valve, f, as shown by iig. 4.

Directly beneath the valve is tl-:e seat h, which is soldered into the base or lower part of the measure a, so that the rim or upper part of the seat h only comes to the surface ofthe bottom of the interior of the measure, and therefore occupying no space-in the inten'or of the measure.

The seat-must be constructed of metal, brass being the best material for the same.

The valve attached to the rod O should also be made of metal', though it can be made of leather.

Fig. 4 is a perspective view of the valvef as it is attached to the rod g, being a piece of rubber which is slipped overthe rod and rests on the top of the valve;

and Ythis figure represents a view of the valvewhen open, or rather when' not shut down into the seat h.

Fig. 3 is a view of the valve when closed, or when shut down into the' seat h. Y When the valve is open, the top of it, or rather the rubber, is brought securely against the bottom of the tube E, as shown in fig. 4.

'By means of the leverd any given quantity of liquid, i

indicated on the index above each lever, cau be drawn from the can by vsimply pressing down the lever :l to the notch just below the lever. The exact quantity indicated .just above the lever will immediately pass out at the faucet f by pressing down the said lever.

The liquid passes from the apartment B into the measures below throughc' c. In order that this aperture at cl c' maynot be obstructed byanything which may be in the liquid, asmall wire screen or peribrated tin is placed around and over c c.

Fig.'2 is an end view of the measuringapparatus,- exhibiting the manner by which each measure maybe regulated to an exact quantity, at any time when it appears to be incorrect.

c/ e is a nut inserted in the end of' each measure, with a'thread on the inside oi it.

C, iu fig. 5is theregulator,which consists of a i straight rod, as indicated bythe two dotted lines in said ligure, at the large end of which lis the screwthread, fm, so constructed as to screw tightly into the nut c e', and the shoulder l, which is `of' rubber, adjoining the thread m, is screwed tightly against thenute e,

thus preventing any liquid escaping.

0n the end of thisregulator is thethread kandnut 0, which is arranged so as to screw and hold to its position thi; thimble z, which is insertedover the rodzz. This thimble may be large or small, according as it may be necessary to increase or decrease the quan tity in each measure. v

Byvmeans oi' a door on the outside of the can, coving the ends of' each measure, in which is inserted the regulator, the sealer of weights and measures may at any time easily regulate the quantity in each measure to his standard by the use of the regulator, as herein explained, and then seal the end of each measure where the regulator enters at c e'.

I he measures, as shown in iig. 1, are constructed one above the other, like stair-steps, and the inside of each is so arranged by slips of tin being soldered on the edge and extending toward the seat g g, as shown in iig. 2, that the liquid runs rapidly toward the seat and out thejfaucet f.

Each measure has a vent which extends to the top.V

and outside of the can A, as shown by a' a', and on the top of the vent is a cap which prevents the forcing of the liquid out of the can, or the ve\uts may be made to come within aboutpone-quarter of an inch oi' tile upper surfaceof the can, and directly over each vent a. small slide may be so made that in case the v ents need cleaning, it maybe easily done by removing the slide.

' In fig. 1, a slide or door is so constructed es to give access to theentire part of the can A below the apertrnent B, so that in ease repairs are necessary, the work may be easily done without delay orinjuring the can, and the measures can beso constructed on my principle as to allow any required quantity of' liquid to be drawn, in the manner herein explained.
